UNITED STATES PATENT WILLIAM J. BURT, OF NILES, OHIO.

COPY-HOLDER.

SPECIFICATION forming` part of Letters Patent No. 672,750, dated April 23, 1901.

Application iiled October Z0, 1900. Serial No. 33,731. (No model.)

To all whom it may concern.:

Be it known that I, WILLIAM J. BURT, of Niles, in the county of Trumbull and VState of Ohio, have invented certain new and useful Improvements in Copy-Holders; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to copy-holders.

The object of theinvention is to provide a simple and inexpensive holder for note-books or tablets of various sizes, the insertion or removal thereof being easily and quickly accomplished.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective, parts being broken away. Fig. 2 is a rear elevation. Fig. 3 is a cross-section on line 3 3, Fig. 2.

Referring to the drawings, 1 designates a rectangular frame mounted in a rearwardlyinclined position upon a base 2 and supported by braces 3. The base 2 is provided with a longitudinal cut-out, wherein is a bracket 4, depending from aplate 5 on said base. A le- 'ver 6 is fulcrumed in this bracket, and to one end of the lever is pivotally secured a rod 7, which is extended through and guided by a keeper 8, secured to a cross-bar of frame 1. This rod at its upper end is connected by two toggles 9 to slides 10, adapted to have a longitudinal movement laterally of the frame in guideways formed by plates 11, secured to a bar 12. These slides are provided with jaws 13, each of which is capable of adjustment on its respective slide to accommodate books,

dac., of various sizes, the means shown comprising a set-screw 14, projected through a slot 15. The gripping-surfaces of the jaws are'serrated in order to insure a firm hold upon the edges of the books.

16 designates a coil-spring encircling and secured at one end to the rod 7, its other end being held to the base-plate. This spring tends to normally hold said rod in a lowered position, with the jaws drawn toward each other. A push-button 17 on the front end of lever 6 projects up through an opening in the base-plate.

In practice when it is desired to position a note-book the button 17 is pressed down, throwing outwardly the slides and their jaws, whereupon the note-book is placed against the frame, and upon pressure being relieved from the push-button the rod 7 will be drawn down by the tension of the spring and the jaws will take a firm grip upon the side edges of the note-book.

The advantages of my improvements are apparent to those skilled in the art. It is obvious that changes in construction may be made without departing from the spirit of my invention. A

I claim as my inventionl. Acopy-holder comprisinga base, aframe thereon forming a rest, engaging and holding means mounted on the frame at the sides thereof, and means mounted on the base and connected to the former means for operating the latter, as set forth.

2. Acopy-holder comprising a base, aframe thereon forming a rest, engaging means at opposite points of said frame, a spring-held rod,

means connecting said rod to said engaging means, and means mounted on the base for operating said rod, substantially as set forth.

3. The combination with the base and the frame, of longitudinally-movable slides, jaws thereon, spring-held means normally holding said jaws toward each other, and means for operating said former means for movingsaid jaws laterally from each other, substantially as set forth.

4. The combination with the base and the frame, of the longitudinally-movable slides, jaws thereon, a rod, toggles connecting said rod to said slides, a spring holding said rod, and means for operating the latter, substantially as set forth. j

5. The combination with the base and the frame, of the longitudinally-movable slides, jaws thereon, a rod, toggles connecting said rod to said slides, a spring holding said rod, a lever to one end of which said rod is secured, and a push-button on the other end of said lever, substantially as set forth.

6. The combination with the base and the plate thereon having an opening, of the inclined frame, the laterally-movable slides on said frame, jaws on said slides, a spring-held rod, toggles connecting the latter to said IOO slides, a lever in said base to which said rod is secured, and ai push-button on the other end of said lever fitted in the opening in the base-plate, substantially as set forth.

7. A frame having a rest adapted to hold a book thereon,a cross-rod provided with guideways, slides adapted to move in said guideways, jaws adj ustably secured on said slides, spring-held mechanism for normally holding said jaws against the sides of a book on said frame, and means for releasing said jaws, substantially as set forth.

8. A frame having a rest adapted to hold a book thereon,a cross-rod provided with guideways, slides adapted vto move in said guide- In testimony whereof I have signed this' specification in the presence of two subscribing witnesses.
